                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

A.                Tampa Electric Company (the company) is a wholly owned
         subsidiary of TECO Energy, Inc.

B.                The company has made certain commitments in connection with
         its continuing construction program. Total construction expenditures
         during 2000 are estimated to be $251 million for its electric division
         (referred to as Tampa Electric) and $75 million for its natural gas
         division (referred to as Peoples Gas System). Tampa Electric Company is
         a potentially responsible party for certain superfund sites and,
         through its Peoples Gas System division, for certain former
         manufactured gas plant sites. While the joint and several liability
         associated with these sites presents the potential for significant
         response costs, the company estimates its ultimate financial liability
         at approximately $20 million over the next 10 years. The environmental
         remediation costs associated with these sites are not expected to have
         a significant impact on customer prices.

C.                Revenues in the three- and six-month periods ended June 30,
         1999 reflected the deferral for refund to customers of $2.5 million and
         $3.9 million, respectively of electric revenues associated with 1999
         earnings at Tampa Electric. These deferred revenues resulted from Tampa
         Electric's regulatory agreement that ended on Dec. 31, 1999. Tampa
         Electric expects the Florida Public Service Commission (FPSC) staff to
         closely monitor the company's achieved return on equity during 2000,
         but not to require Tampa Electric to negotiate a new regulatory plan.
         On Aug. 1, 2000, the FPSC approved a stipulation entered into by the
         Office of Public Counsel, Florida Industrial Power Users Group (FIPUG),
         and Tampa Electric settling the deferred revenue refund amount for 1997
         and 1998. From Sept. 1, 2000 through Dec. 31, 2000, Tampa Electric will
         refund $13 million to its customers which was the amount originally
         approved by the FPSC for the years 1997 and 1998. As a result, this
         amount was anticipated and recorded in earnings before the FIPUG filed
         its protest in which the stipulation was reached. The exact amount of
         the 1999 refund is expected to be settled by year end. Tampa Electric
         does not expect these refunds to have a significant impact on earnings.

ITEM 2.  MANAGEMENT'S NARRATIVE ANALYSIS OF RESULTS OF OPERATIONS

         This Quarterly Report on Form 10-Q contains forward-looking statements
which are subject to the inherent uncertainties in predicting future results and
conditions. Certain factors that could cause actual results to differ materially
from those projected in these forward-looking statements include the following:
general economic conditions, particularly those in Tampa Electric's service area
affecting energy sales; weather variations affecting energy sales and operating
costs; potential competitive changes in the electric and gas industries,
particularly in the area of retail competition; regulatory actions affecting
Tampa Electric and Peoples Gas System; commodity price changes affecting the
competitive positions of Tampa Electric and Peoples Gas System; and changes in
and compliance with environmental regulations that may impose additional costs
or curtail some activities. Some of these factors are discussed more fully under
"Investment Considerations" in TECO Energy's Annual Report on Form 10-K for the
year ended Dec. 31, 1999, and reference is made thereto.

RESULTS OF OPERATIONS

THREE MONTHS ENDED JUNE 30, 2000:

         Tampa Electric Company's net income for the quarter ended June 30, 2000
was $39.7 million, up from $38.1 million for the three-month period ended June
30, 1999. The 4 percent increase over last year's net income reflects revenue
growth at Tampa Electric and Peoples Gas System. Consolidated operating income
from continuing operations was $56.5 million compared with last year's operating
income of $54.3 million.

TAMPA ELECTRIC COMPANY - ELECTRIC DIVISION (TAMPA ELECTRIC)
         Tampa Electric's net income for the quarter increased approximately 3
percent, driven primarily by improved retail energy sales volumes, which were 6
percent higher for the quarter, partially offset by higher costs. Growth in
retail customers was 3 percent. Expenses for the quarter increased, reflecting
higher depreciation and accelerated maintenance expenses to enhance summer unit
availability. Prior year results were favorably impacted by U.S. Department of
Energy credits associated with the Polk Power Station, which expired at the end
of 1999. Results for the current quarter include the favorable impact of cost
recovery from the scrubber investment at Big Bend Station, which was placed into
service in December 1999. A summary of the operating statistics for the three
months ended June 30, 2000 and 1999 is below:

         A generator failure caused an unplanned outage at Tampa Electric's
385-megawatt Gannon Station Unit 6 on July 18, 2000. The unit is currently being
repaired and is expected to be back in service by the end of 2000. Tampa
Electric has been purchasing and expects to continue to purchase replacement
power to meet peak loads until the unit returns to service. The estimated
replacement power costs of approximately $20 million is expected to be fully
recovered through the fuel adjustment cost recovery clause.

It is expected that most of the repair costs will be covered by insurance and
the remaining amount will be capitalized. As a result, the outage is not
expected to have a significant impact on Tampa Electric's operating income.

TAMPA ELECTRIC - NATURAL GAS DIVISION (PEOPLES GAS SYSTEM)
         Net income at Peoples Gas System (PGS) increased 19 percent to $4.1
million for the quarter ended June 30, 2000 compared with $3.4 million for the
same period last year. The increase was driven by customer growth of 4 percent
and corresponding higher volumes. Commercial volumes were up 5 percent, while
residential volumes were down slightly. Lower margin sales to interruptible
wholesale and electric power generation customers were up 23 percent.
Depreciation was higher reflecting the company's continuing expansion efforts,
while operation and maintenance expenses were essentially even with last year. A
summary of the operating statistics for the three months ended June 30, 2000 and
1999 is below:

         The franchise agreement between the City of Lakeland and PGS expired on
March 12, 2000. The City has suspended negotiations for a renewed agreement;
however, normal operations in Lakeland have continued under the terms of the
expired agreement. Lakeland provided approximately $2 million of PGS' annual
operating revenues in 1999.

OTHER
         Allowance for other funds used during construction (AFUDC) was $0.7
million for the three months ended June 30, 2000, up from $0.2 million for the
same period last year. AFUDC is expected to increase over the next several years
reflecting Tampa Electric's generation expansion activities.
         Interest charges were $17.5 million for the three months ended June 30,
2000 compared to $16.0 million for the same period in 1999. Financing costs in
the second quarter reflected increased short-term borrowings and higher interest
rates on those borrowings.

SIX MONTHS ENDED JUNE 30, 2000:

         Tampa Electric Company's year-to-date net income was $76.8 million, up
from $72.8 million for the six-month period ended June 30, 1999. The 5-percent
increase over last year's net income reflects revenue growth at Tampa Electric
and Peoples Gas System. Consolidated operating income from continuing operations
was $110.4 million compared with $103.8 million last year.

TAMPA ELECTRIC COMPANY - ELECTRIC DIVISION (TAMPA ELECTRIC)
         Tampa Electric's year-to-date net income increased to $64.3 million,
compared to $62.1 million for the same period last year. The approximate
4-percent increase was driven primarily by improved retail energy sales volumes,
which were 7 percent higher year-to-date. Growth in retail customers was 3
percent. Year-to-date expenses increased over last year reflecting higher
depreciation and accelerated maintenance expenses to enhance summer unit
availability. Prior year results reflected U.S. Department of Energy credits
associated with the Polk Power Station, which expired at the end of 1999. A
summary of the operating statistics for the six months ended June 30, 2000 and
1999 is below:

TAMPA ELECTRIC - NATURAL GAS DIVISION (PEOPLES GAS SYSTEM)
         Net income at Peoples Gas System (PGS) increased 17 percent to $12.5
million for the six months ended June 30, 2000 compared with $10.7 million for
the same period last year. The increase was primarily driven by customer growth
and corresponding higher volumes. Commercial volumes and residential volumes
were up 9 percent and 11 percent, respectively, for the year. Lower margin sales
to interruptible wholesale and electric power generation customers were up 26
percent year-to-date. Depreciation was higher reflecting the company's
continuing expansion efforts while operation and maintenance expenses were
slightly higher. A summary of the operating statistics for the six months ended

OTHER
         Year-to-date allowance for other funds used during construction (AFUDC)
was $1.0 million compared to $0.2 million for the same period in 1999. AFUDC is
expected to increase over the next several years reflecting Tampa Electric's
generation expansion activities.

         Interest charges were $34.7 million for the year-to-date period ended
June 30, 2000 compared to $31.5 million for the same period in 1999. This
increase is a result of higher borrowing levels and interest rates.

RECENT DEVELOPMENTS
         On May 3, 2000, the governor of Florida by executive order created a
commission charged with proposing a comprehensive energy plan and strategy for
the state. The 17 member Energy 2020 Study Commission will address issues
including the current and future reliability of electric and natural gas
supply, emerging energy supply and delivery options, electrical industry
competition, environmental impacts of energy supply, energy conservation, and
fiscal impacts of energy supply options on taxpayers and energy providers. The
Commission will convene its first meeting in September 2000, and will provide a
written report containing specific recommendations, including legislature
recommendations, by December 1, 2001.

ACCOUNTING STANDARDS

ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING
         In 1998, the FASB issued FAS 133, Accounting for Derivative Instruments
and Hedging. This standard is effective for fiscal years beginning after June
15, 2000. The new standard, as amended, requires an entity to recognize
derivatives as either assets or liabilities in the financial statements, to
measure those instruments at fair value and to reflect the changes in fair value
of those instruments as either components of comprehensive income or in net
income, depending on the types of those instruments.

         In preparation for adoption of this Statement effective Jan. 1, 2001,
the company has completed an analysis of the information required by FAS 133,
and is continuing to evaluate and document all derivatives and hedging
relationships. From time to time, Tampa Electric has entered into futures, swaps
and options contracts to limit exposure to gas price increases at both the
regulated natural gas utility, and to moderate its exposure to interest rate
changes. The benefits of these arrangements are at risk only in the event of
non-performance by the other party to the agreement, which the company does not
anticipate. The company does not anticipate that the adoption of FAS 133 will
significantly impact its financial statements since activity in derivatives has
been relatively minimal and short-term in duration. Management will continue to
evaluate all current and possible future uses of derivatives, including their
effectiveness for hedging, and to apply appropriate procedures and methods for
valuing them.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk
         Tampa Electric Company is exposed to changes in interest rates
primarily as a result of its borrowing activities. A hypothetical 10-percent
increase in Tampa Electric Company's weighted average interest rate on its
variable rate debt would not have a significant impact on Tampa Electric
Company's pretax earnings over the next fiscal year.

         A hypothetical 10-percent decrease in interest rates would not have a
significant impact on the estimated fair value of Tampa Electric Company's
long-term debt at June 30, 2000.

         Based on policies and procedures approved by the Board of Directors,
from time to time Tampa Electric Company may enter into futures, swaps and
option contracts to moderate exposure to interest rate changes.

Commodity Price Risk
         Currently, at Tampa Electric and Peoples Gas System, commodity price
increases due to changes in market conditions for fuel, purchased power and
natural gas are recovered through cost recovery clauses, with no effect on
earnings.

         From time to time, Peoples Gas System may enter into futures, swaps and
options contracts to limit the effect of natural gas price increases on the
prices it charges customers.

         Tampa Electric Company does not use derivatives or other financial
products for speculative purposes.
